CW276A Cylinder Thermostat is an automatic valve with remote temperature sensor. Fitted to a C-Warm marine water storage heater (calorifier) it limits the temperature of the stored hot water to a pre-set maximum (normally 55°C) by restricting the flow of engine cooling water through the coil.
Connections: 15mm compression fittings.
CW276A is for use with indirect-cooled marine engines, with the engine and the heating coil in parallel in the engine cooling circuit. (For direct-cooled engines, use CW289A Cylinder thermostat with by-pass).
The sensor is attached to the copper wall of the C-Warm heater. A rise in temperature causes the liquid in the sensor to expand, forcing it through the capillary tubing connecting the sensor to the valve, and progressively closing the valve. The flow of hot water from the engine cooling circuit through the coil of the calorifier is reduced and eventually stopped, restricting the stored water temperature to its pre-set maximum.
